Got some news to add now.

Finally got the machine to stay on and was replicating the orginal posters problem exactly.

To get to that point all I did was take out the CPU and then replace the CPU ... and put it back exactly how it was before. Even though it shut off after 20 seconds I still viewed it as progress. Though was pretty bummed when it happened because at first I thought it was just going to stay on.

So, after doing this a few times I think it is the PSU. The machine seemed to shut off whenever the HD started spinning up. Well, I wanted to test a few times to see if that was indeed what was going on ... I had planned on unplugging the HD to see if it would stay on but before I got the chance one of the times I started it up I got a bright flash of light from the PSU and now I'm not getting any power at all. (Guessing something blew ... I hope it didn't fry anything else). I didn't get smoke or anything so ... at least that's a good sign.

Unfortenately I hadn't hooked a monitor up to it yet so I don't know how far into the booting process it got. I guess I'm getting a new PSU now ><

I'll keep you guys posted.

Got a new PSU and it's staying on.

I recommend getting one that is 24-pin. I don't know how far I'm getting into the bios at this point, but I know it's staying on.

Doesn't matter what I have plugged in ... after 20 seconds it shuts down. How very very annoying. No beeps, no clue as to what it is ... back to thinkin' it's the MB ><

Yeah, I've had a problem like this with a motherboard before.

The MB is really the only part that me and the orginal poster have in common ... ah well, that other PSU was crap anyway.

My best guess for you is what i said earliar and that it is a heat problem or a bad component, best bet is to pull it out throw it on a piece of cardboard with cpu 1 stick of ram and video card if u are using one that will tell you if it the mobo or if it is overheating.

I don't know, but I'm not too mad about it (Other than I wasted my time working on it).

I bought the motherboard "Open box" from newegg (Which means it was used and got sent back for something).

I paid $15 bucks for the thing so I'm not all that concerned about it. You can wait until I replace mine to see if it's the problem (Just got a different brand, new this time ... lesson learned ... ) and if it's still dorked up it's not the MB.

I can almost garentee that's the problem though (I've seen similar behavior with a dorked MB before). The odds are just too great against it being something else, as that is the only part we have in common and we're having the same identical problem.

You can wait to see what happens with my system, but I'd start going through ebay's channels if you're interested in getting your money back.

I had a similar problem, and it turned out to be over heating. I actually cracked a tiny piece off of the plastic arm used to puch the heatsink down without noticing. Therefore the heat sink wasnt completely touching the processor. My pc shut off in about 20 seconds. I bought a new heatsink for like $20-30 and its worked like a charm. Also artic silver 5 helped.

My motherboard literally came with some of the small pins in the socket bent with two bright red stickers pointing to the bend ...

It's not rocket science to figure out that could be the problem, but I trusted the manufacturer who said it should still function with that defect. Oh well.
